Parity violating elastic electron-nucleus scattering provides an accurate and model-independent measurement of neutron densities, because the [Formula Presented] couples primarily to neutrons. Coulomb distortion corrections to the parity violating asymmetry [Formula Presented] are calculated exactly using a relativistic optical model. Distortions significantly reduce [Formula Presented] in a heavy nucleus. However, even with distortions, an experiment to measure the neutron radius is feasible. This will aid the interpretation of future atomic parity violation measurements and provide fundamental nuclear structure information. Coulomb distortions and small differences between neutron and proton radii could be important for a standard model test on [Formula Presented], [Formula Presented], or [Formula Presented].
